Sony says the new lenses “deliver significant improvements in image quality, ghost reduction and AF performance” over the previous models and feature a more rugged and dust- and moisture-resistant design.

The new lenses are designed to pair with Sony’s premium A99 and A77 II cameras.

The new lenses also feature enhanced AF capabilities compared to their predecessors, and deliver approximately 4x the subject tracking speed because of their SSM (Super Sonic wave Motor) system and faster, more powerful processing in the lens LSI.
